What exactly is a grandfather clause?
Very simply: Grandfather = Old. So, there is a NEW CLAUSE that is a change from what the OLD CLAUSE used to be. Such as a house in 1950 could be built with up to 3 stories on the beachfront. BUT, now the law may be changed so that it only allows a 2 story home to be built. Since the home was built in 1950, it is not subject to the new law (zoning restriction or clause). This would be a case of “grandfather clause.” The old home is subject to the old law.
